The first episode of House M.D. is titled “Pilot.”
“Pilot” introduces Gregory House, his diagnostic medicine team, and the fictional Princeton-Plainsboro Teaching Hospital. The episode follows a kindergarten teacher who becomes ill, and House’s team works through competing explanations while House challenges conventional assumptions about the case.
The episode establishes the series’ core formula: a difficult medical mystery, a team of specialists, House’s unconventional reasoning, and conflict with hospital authority. It also introduces major early characters including James Wilson, Lisa Cuddy, Eric Foreman, Allison Cameron, and Robert Chase.
“Everybody Lies” is strongly associated with the series because it is House’s recurring maxim and also the title of the finale. “Three Stories” is the season-one episode that won a major writing award, while “Occam’s Razor” is the second episode. Those titles are therefore plausible mix-ups but not the title of the premiere.
